This invention relatesto conveyers and particularly to an apparatus designed to -facilitate the transference 'of loose coal infafmine to the cars in ywhich'. itis transported" from the'mine. f f

In present-day methods of mining-*coal/a `so-called short-Wall? or long Wall mining machine is usedto undercut the body O'f coal. The coalis'then shot down and rests ina loose mass of fragments against the face of the seam. v- The handling of this loose coalentails a great deal of labor and expense."y Attempts havev been made heretofore tol provide a conveyer which vcan be moved into the loose mass of coal topick it upmore or less automatically and conveyit to the cars on the mine tracks.

The apparatus heretofore devised for this.

y purpose' lis relatively complicated, l' cumbersome and expensive. 'While it'v iscapable fof transporting the coal to the cars itis not casi-2 ly handled and moved from place to placegasV required@ l Itis Vthe obj ect yof the present invention to provide a simple and 'satisfactory conveyer which will facilitate thetransferoffthe coal from the face ofther seam tothe cars and `Which can bemoved easily as the miners fadvance in Working the. seam.

Thefconveyer lgfvvhich is hereinafter de-v scribedv inlmore detail is'arranged parallel to -the face and is adapted to be forced by a pluu ,fralityofj acks14 which restagainst the tim- *fbersflgunderpthe mass 7 of broken coal. The

4*Theconveyer `l31com`prises a plurality lof :sections 15 which are connected by section splicers. 16. The sections include a bottom #pl-ate 17 an'dtop'plate l`8 Which are held in ,spaced4A relation .by angles 19v and 2Oy secured `itoar sidelfplate 2land vby an angle22; The

topiplate' 18 ,has asloping face 23, extending to thebottoin, plate 17 anda plurality of loosening;bits @Aare secured at intervals'to .the iwedgesshapedhousing formed by the top soV fand bottoin'plates to facilitate the introduci itionugof .the conveyer beneath the body ofV s .':A'fchain disposed about the sprocket 26 iat one 'end ofthe conveyer on ay shaft 27.

After passing over the sprocket the flights return with 4top plate is supported by angles securedf to the motor base plate 37.

Each of the flights is provided Witha U-` shaped section 38 adapted to 'straddle the chain 25. The flights are secured by bolts which pass through the chain. The structure permits the'even distribution of the load to the chain. t Y

The operation of the conveyer will be understood readily from the foregoing description. When the coal has been shot down, the conveyer which has been arranged in parallel relation with the face of theseam is moved forwardly by means of the jacks 14: until the looseningV bits 24 and the top plate 23 are beneath theiloose coal at thefront of the mass. The motor is then startedand the flights advance along the` top plate carrying the coal with it and discharging it upon the drag conveyer v11. The conveyer is moved from time to time toward the face of the seam by Voperating the jacks 14 until allV of the loose coal has been picked up by the conveyer and transferred to the car. The face of the seam is Vthen vexposed and the operations of undercutting and/of shooting down the coal can be repeated, afterwhich the conveyer is again placed in operation to fremove the loose coal. Y

Y The structure ofthe conveyer as hereindescribed is simple and it can be constructed and operated at a relatively low cost. It is efficient in operation and permits vthe removal of the loose coal rapidly so that the face of the seam is exposed for further operations vwithin a comparatively short time. The parts of the conveyer may be of sturdy construction suitable for `the rough usage tol which it is subjected. There are few parts Vand these are notlilrely to break; If broken the parts can be repaired orreplaced easily.

v The 'preferred structure ofthe conveyer is illustrated and described herein, but various changes can bey made in the details of con-v struction and arrangement of the parts without vdeparting fromY thev invention or sacril vficing any of the advantages thereof..r
